Lol, same here. My code is broken because of the same approach. But
these changes will cause me to delete most of my stuff, so the rework
should be pleasant.

I suspect that EditView will need a few protected methods for this sort
of thing, but trivial stuff really.

I wanted to change the codebase as little as possible (sersiously :-) so
I didn't bother with these sort of use cases. But should be much easier
now.
